A lifesaving tool for covid patients using BPF soft topology: decision making in oxygen concentrator

Abstract

In this paper, we introduced the notion of bipolar Pythagorean fuzzy soft topology and proved some of its basic properties. We defined bipolar Pythagorean fuzzy regular generalized soft sets. We presented some basic operations on bipolar Pythagorean fuzzy soft topology. We gave an application of bipolar Pythagorean fuzzy soft open sets which are bipolar Pythagorean fuzzy regular generalized closed sets taken from bipolar Pythagorean fuzzy topology into a decision-making problem.
